Title: Surface coated, titanium carbide group cermet cutting tip for threading and grooving
Inventor: KATO MUNENORI
IPC: B23B27/14
Filed: 1988-03-07
Abstract: PURPOSE:To aim at enhancing the life of a cutting tool by forming a hard coating layer made of solid solutions of carbide and nitride of Ti and Zr on the outer surface of a cermet base having a surface roughness of 0.1-0.5mum. CONSTITUTION:TiCN group cermet cutting tool is formed so as to have a surface roughness of 0.1-0.5mum. Among Ti, Zr carbide and nitride and more than two kinds of solid solutions thereof, one kind thereof is used for a single hard coating layer while two kinds thereof are used for multiple hard coating layers by an evaporating process, on the outer surface of the cutting tool. With this arrangement, the hard coating layer is firmly bounded to the outer surface of the cutting tool, no peeling and chipping occur during machining, thereby it is possible to greatly enhance the life of the cutting tool.

Title: Optical modulating element
Inventor: INABA YUTAKA
IPC: G02F1/1335
Filed: 1986-03-11
Abstract: PURPOSE:To obtain good display quality and to improve display contrast by setting the angle of a molecule axis to the axis of polarization of a polarizer when the optical modulating material of a picture element part is oriented with an electric field having the same polarity with an electric field smaller than the angle of the molecule axis to a center axis. CONSTITUTION:When the molecule axis 55 of ferroelectric liquid crystal at a part where there is no picture element is oriented in one stable state with an applied voltage with one polarity (positive voltage), the angle theta1 of the molecule axis 53 when ferroelectric liquid crystal at a picture element part is oriented with the positive voltage having the same polarity with the applied voltage to the axis 51 of polarization of one polarizer is set smaller than the angle theta2 of the molecule axis 53 to the center axis 56. When display quality is considered, the angle of the molecule axis 55 at the part where there is no picture element to the axis 51 of polarization is settable to or almost to 0 deg.. The molecule axis 53, however, need for be made parallel to the axis 51 of polarization and the axis of the molecule axis 53 to the axis 51 of polarization is only set smaller than the angle of the molecule axis 55 at the no-picture-element part to the axis 51 of polarization.

Title: Thermal head
Inventor: SASAKI KAZUNARI
IPC: H01L49/00
Filed: 1983-03-31
Abstract: PURPOSE:To prevent the occurrence of cracks in a wear-resistant protective film by covering the first lead wire except for the second lead wire and a heating section with the wear-resistant protective film. CONSTITUTION:A heating resistor layer 3 formed on an undercoat film 2 of an aluminum base plate 1 is partly exposed to form a heating section 8, and the first lead wire 4 made of an active metal such as chromium, titanium, etc., is formed. The second lead wire 5 made of a conductive metal such as gold, aluminum, etc., is formed on the lead wire 4 away from the end 31 of a wear-resistant protective film 7 formed on the heating section 8 and also on the boundary between the lead wire 4 and the heating section 8. Since the wear-resistant protective film 7 is not formed on the lead wire 5, a danger of occurring cracks from the end 22 of the lead wire 5 to the wear-resistant protective film 7 due to the slide movement of a heat-sensitive paper 21 on the heating section 8 can be eliminated. The preferred distance between the end 31 of the wear-resistant protective film 7 and the end 22 of the lead wire 5 is about 1-5mm..

Title: Printing head
Inventor: FUKUCHI HIROMICHI
IPC: B41J2/055
Filed: 1981-04-09
Abstract: PURPOSE:To provide an on-demand type printing head which has been improved not to generate satellite spots even if ink jetting speed increases by providing a capacity chamber having a small capacity between a jet nozzle hole and a pressure generating chamber. CONSTITUTION:Both ends of a pressure generating chamber 12 which generates pressure for making ink droplets are narrowed down by small diaphragms A1, A2 and a capacity chamber 13 of which capacity is very small comparing with the pressure generating chamber 13 is provided between the diaphragm A1 and a jet nozzle 11. When electric signals are applied to a piezoelectric vibrator 16, a flexible plate 15 deflects and generates shock waves in the pressure generating chamber 12. Shock waves are conveyed to the capacity chamber 13 through the diaphragm A1 where high frequency components are removed, therefore an ink flow of less disturbance is spouted from the jet nozzle hole 11. Moreover, even if air enters through the nozzle hole 11, it is prevented from entering the pressure generating chamber 12 as such air is caused to stay in the capacity chamber 13.

IPC: B22C9/06
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a method for predicting a thermal fatigue life of a die based on a material characteristic and a thermal stress load of a die. SOLUTION: In this method, temperature distribution of a heated die is obtained by contacting with a workpiece, and thermal stress distribution generated to the die is obtained from the temperature distribution. A thermal fatigue life at a given position x of the die is predicted from temperature Th in the heating time at the given position x of the die, thermal stress σn and proof stress σy(Th) at the temperature Th of the die material, and a drawing ϕ(Tc) at the temperature Tc during cooling. Preferably, a relation formula of the die thermal fatigue life N, Th, σn, σy (Th), and ϕ(Tc) will satisfy N= C1(σy(Th)/σn)m.1n(1-ϕ(Tc))-1-C2}n, where C1, C2, m, n are constants. Further preferably, the temperature distribution and the thermal stress distribution are obtained by a finite element method.

Title: Electrode of compound semiconductor element
Inventor: ONABE KENTAROU
IPC: H01L29/45
Filed: 1983-03-30
Abstract: PURPOSE:To reduce boundary energy level density and to alleviate the generation of a crystal dislocation by using metal electrodes of plane core or cubic core structure substantially equal to 1/2.2<1/2> or 1/2 of lattice constant of InP single crystal. CONSTITUTION:When metal matched with crystal lattice on InP single crystal (001) plane is epitaxially grown, a boundary energy level density decreases, to prevent the crystal dislocation, but there is no metal which coincides with lattice constant a0 of InP. However, when the lattice constant of plane core cubic structure is equal to a0/2.2<1/2>, or when the lattice constant of a plane core cubic metal is equal to a0/1, similar effect is obtained. Accordingly, when metal which coincides with these values within 3% of error such as Ag, Fe is used, the boundary energy level density can be reduced.

Abstract: PURPOSE:To prevent a sound signal from being misjudged as a control signal by judging that the control signal is contained in an input signal in the case that the power value of a specified frequency component and the ratio of the power values are over prescribed values. CONSTITUTION:A CNG signal judgement circuit 10 inspects whether the mean power value P2 of only the frequency component the same as a CNG signal in an input signal maintained a value over a second normal value C2 for second normal time T2 a little under 0.5sec or not, and simultaneously, it inspects whether the ratio P2/P1 (where P1 is mean power value of whole input signal) maintained the value over a first normal value C1 for first normal time T1 shorter than 0.3sec during this period or not. Namely, it inspects a property that the CNG signal is continued at a level higher than -43dBm for 0,5sec, and besides, it inspects the property that the CNG signal is the single sine wave signal of 1100Hz+ or -38Hz. Then, in the case that both of these power value P2 and ratio P2/P1 are maintained, the input signal is judged to be the CNG signal.
